Electrical busways The electrical busway is a modular, overhead electrical distribution system that supplies power to the HP POD 20c IT loads. The HP POD 20c includes two busways and each busway can support 200 A. Top view shown The HP POD 20c electrical busways can be configured for non-redundant power or redundant power. The HP POD 20c can be installed as a single source 1N load by providing all required feeders from one common power source and from common switchboards and transformers.
Redundant power installation (2N load)—Each busway is powered through parallel power paths from independent power feeds. Drop boxes The internal electrical busways provide a location to connect each of the drop boxes, which then power the PDUs. Stagger the drop boxes on the electrical busways by connecting one drop box to busway #1 and connecting the next drop box to busway #2. A staggered configuration enables load balancing with the rack equipment and is necessary to ensure redundancy.
• To disable power to a single busway, open the appropriate breaker for that busway on the corresponding electrical busway panel on the HP POD 20c exterior. • To disable power to all racks, open the breaker for each busway on the corresponding electrical panel on the HP POD 20c exterior. Power configurations IMPORTANT: Different PDUs can alter the average power capacity per rack.
A light switch is located at every personnel door. For more information on light switch locations, see "Life safety component identification (on page 10)." All six lights are connected to battery backup power, keeping the interior of the HP POD 20c illuminated during a power outage or emergency. For more information on lighting, see the HP Performance Optimized Datacenter 20c Maintenance and Service Guide.
Environmental control system Environmental control system overview The ECS developed for the HP water-cooled POD is a stand-alone control system that requires no external connections with an external site system, BMS, public or private Internet sites, cloud, or wireless system to properly control the POD operation. The ECS includes Modbus TCP/IP connections through which a variety of data can be retrieved.
By connecting your HP POD 20c to a BMS system, you can monitor the various parameters and alarms. For more information, see "Navigating the ECS interface (on page 39)." The complete list of parameters and alarms that can be monitored will be discussed with your facilities personnel.
